This is simply wrong, the 3GP uses 3G and the MIB2/MHI2 uses 4G!Hello
I like that with the cards very much. The connection of the cards in the MMI is still limited. since only 2G works after the 3G subscription, this will probably not work with the map download either. A maximum of 10kb / s is transmitted via 2G. that will hardly be enough for the cards
because your unit is retrofit if the old one didnt had connect package then Sat Map will never work thru Audi.
There is option to downgrade to 3638 and then use Google (check the other thread about details).
This is only if you want to use Google/SatMaps.
